Energon drone

Energon drones are robots from the live-action movie continuity family.

Energon drones are insect-like non-sentient robots either created or corrupted by the All Spark.

Games

Transformers The Game

When Bumblebee infiltrated the Sector Seven base within Hoover Dam and managed to release the locks on the All Spark, stray energy bolts began to leap from the cube as it slowly shrank, creating a swarm of Energon drones. Bumblebee was forced to defend himself against the critters... and Sector Seven artillery... and a defrosting Megatron! Oy!

Escaping with the All Spark, as Bumblebee drove through Mission City with the cube in his backseat, it radiated Energon in massive amounts, which coursed through the Energon drones which were standing around on the sidewalk for no apparent reason. The drones followed and swarmed Bumblebee, who crashed into a building and had to be saved by Ironhide. While the Energon drones were small, weak, and only armed with a single machine gun, they came in great numbers. Ironhide won anyway.

Another group of Energon drones also attacked Scorponok in a nearby park, but were destroyed. Transformers The Game (console)

Transformers: Autobots video game

As Bumblebee retrieved the AllSpark from the Dam, the Cube sent out bolts of energy that turned whatever they hit into Energon Drones. To defend itself. From being saved. Yeah.

Best ignored, the safest thing to do was just grab the cube and run like the wind before the lil insects caught up with 'Bee.

When attacked, the smaller robots will explode and damage anything nearby, and if a larger Transformer is close enough, he'll be thrown back by the explosion.

Transformers: Decepticons video game

Possessing the AllSpark, Starscream has the ability to create and control Energon drones (here called Spark Drones) and sends waves of them after Create-A-Bot. However, being weak, small, and made of rusted out old vehicles, they easily fall to Create-A-Bot's blaster.

They later appear in both Autobots and Decepticons in a challenge mission, "Drone Extermination".

Notes

• The don't appear to have an alt-mode, which is essential for all mutations spawned by the Allspark
• Instead they are just sitting, deactivated on the sidewalk
• They resemble giant metal crickets
• Energon drone's machine guns can cause quit a bit of damage if you try and take on too many at once
• They are least satisfying to destroy, when they are hit with only one of two shells of your light guns, they will explode and vanish. Most other drones will explode and spew bits of metal all over the battlefield
